to cause the flow of current impulses through any individual circuit ata rate proportionate to the rate of wages, for example, of the Workmanassigned to that circuit and the individual register included therein. Ihave found it desirable to cause an impulse to How through an individualregister whenever the workman assigned to that register has earned onecent in wages. The result has been a plan of operation which I have cometo designate as the cent-per-impulse The details of the mechanism forcausing this cent-per-impulse operation will be more clearly understoodfrom the detailed description which is to follow. In orderto take careof half-cent rates of wages, the selector switch may be operated on atwo-hour basis; other fractional rates may, in like manner, be takencare of by actuating the selector switch on other bases or periods oftime within which a cycle is completed.

Among the advantages of the system here in disclosed may be mentionedthe fact that the actual flow of current is, in every instance,commenced or stopped by a single switch located at a single place. It istherefore necessary to provide only a single switching device, capableof withstanding the sparking or arcing which is inherent in theoperation of electromagnetic mechanism in circuits of this kind. Thisadvantage is closely connected with another, namely, the fact that theswitching members of the distributing commutator or selector need not beshifted while current is flowing therethrough.

My invention provides a very flexible means whereby any workmans rate ofwagesfas shown byhis wage register, may readily by changed by alteringthe connection of the individual. circuit with the rate controllingmechanism. The circuits of the rate controlling mechanism are made toterminate in spring jacks, or switch contacts. there being a group ofjacks or contacts individual to each rate of wages. It is, there fore,only necessary to connect the terminal of the workmans individualcircuit with the proper spring jack or contact, in order that his Wageregister will be actuated at a rate corresponding with his rate ofwages. Not only do I provide a series of jacks for the regular rates,but. in association with each set ofregular time jacks or contacts, Iprovide a set of overtime jacks, the ratio being one to one and aquarter, or one to one and a half, in accordance with the practice ofthe parties using the system. This arrangement of the jacks makes it asimple .maamr to change a workman from the regular rate to the overtimerate, or viceversa, and to insure the correctness of the rates withwhich the registers will be actuated, under all circumstances.

' My invention provides also an improved means for running the impulsecontrolling mechanismat a speed one-fourth or one-half higher than theregular speed, in order that all of the registers will be actuated atthe increased rate if at any time such more rapid actuation is requiredthroughout the system.

My invention provides a novel and effective means for governing the rateof operation of the impulse controlling mechanism by means of a wellregulated clock.

Another featureof improvement incorporated into my present system is ameans for starting and stopping the operation of the impulse controllingmechanism at pre determined hours of the day; for example, starting themechanism at seven oclock in the morning and stopping it at twelve,noon, this being done automatically, without care on the part of anattendant.

In accordance with my present invention, the workmens time registers areactuated .simultaneously, the totalization of the time being effected bythe operation of a keyboard and suitable totalizing mechanisms inassociation therewith. This or similar keyboard mechanism may, in likemanner, be utilized in effecting other totalizations, as, for example,the total of the wages, if desired. One of the novel features associatedwith the keyboard and its use is the means and method of advancing theindividual registers to their zero position when they are to be re-set,this forward-resetting of the registers being substituted for thebackward or return movement of the regis- 100 ters to the zero positionas contemplated in some of-the earlier systems. This forward re-settingis accomplished by means of the keyboard mechanism, without therequirement for circuit controlling switches asso- 10o ciated with theregisters themselves.

When the individual registers are setforward to zero, their readingsmay, in accordance with my invention, be totalized by transferring to atotal register the com- 110 plements of the readings of the individualregisters, the proper order wheel of the totalizing register beingcounter-actuated one step or unit for each individual register which iscleared. In this conjunction, one 116 of the useful features of myinvention is the association with each of the individual registers ofaspring jack or other set of switch contacts, whereby the terminals of aresetting circuit or impulse mechanism may 1 0 be connected directlywith any individual register, to re-set it to its zero position.

Another important feature of improve ment of my present invention is themethod and means for transferring between various totalizing registers,for the purpose of actuating the registers in accordance with theaccounting results which it is desired to secure. The summations andsubtractions as between the various registers are effected by the use ofa keyboard controller. and plug and jack or other switchinginechanisnrfor establishing connections with the required registeractuating mechanisms. The ke vboard mechanism serves also an importantfunction in periiiittin; other charge se h as charges or deductioi'rsfor material. to be added or suhtraettal from the readings of thejobwost registers. ()ne of the more important mechanical conihii'iationsilit'oi' porated into thekevhoard controlling mech anism is a devicewhich l have called a multi-ratio ditl'ercntial gear. ()ntof the manyuses to which this noiel gear ma;- he put will be more fully understoodfrom the detailed description which is to follow.

I shall take up first the detailed deseription of the circuits andmechanisms for actuating the individual registers assigned to thevarious workmen. Before proceed ing to the details, it may be well toexplain generally that a time register and a wage register are assignedto each workman. Fach workn'ian's time and wage register are connectedin circuits controlled by a manti all operable switch, this switch beingwithin the control of the workman, whereby he may start and stop theoperation of his registers in accordance with the hours during which heis at work. A timekeeper or superinteinlent has control of the terminalsof the workmens individual circuits. and ea h of these he may connectwith a source ol" current. impulses of the proper rate. The, foreman,whose business it is to assign the individual workmen to the jobs inprocess, has control of a. switchboard comprising spring" jacks. whichform the terminals of the job register circuits. and plugs. which harmthe terminals of the individual worknicns circuits. 'lhere is also astrip of spiing jacks whi h forms the terminal of the circuit of a wastewage register. and the foreman must complete each individual circiiiteither through some job register or through the waste wage register inorder that the individual time and wage Fcgisters will he actuated tocredit the workn'ien with the wages to which they are entitled. 1 shallnot attempt to describe the totalizing circuits and mechanisms. until iha\e desci ihed a, little more in detail the indiv dual iicuits andregisters. and the nit-am t'or rci iaiiii; them.

H ts. fl. :iiiillustration, it is to hiso-o that th rate plug Ill may he insert d inhe ]Hil|; ja k 1, as in dicated in dotted l|lll\ and assuming. tor themoment. that this print! jack connects with a source ot' urrent itlliltl-t.-. a circuit may be traced from the plug ltl" through the twolower con act of the switch 5. thence through the clcctroinanni-tic actuatin; mechanism ol' the indiiidiial register \Y. thence through the wire3 which leads to the segment C. of the selector switch. From thissector, the circuit may he traced through the associated brush in themetal AW AWN...

shaft 3, thence to the brush which is in connection with the sector C ofthe other commutator of the pair which forms the selector switch. Fromthis point, circuit may be traced to the plug FP of the foremansswitchboard. For the. present, it may be taken for granted that thisplug may be inserted in a spring jack which completes and closes thecircuit from the source of current impulses not yet described. If, as isthe case, a current impulse is sent over the circuit just traced everytime workman No. 1 has earned one cent in wages, his wage register willat the end of any period or any number of working periods show the totalof the wages earned.

It should be understood, in this connection, that the act of closing theswitch S serves also to set in operation the associated time register TSuch operation is due to the closure of a circuit which may be tracedfrom the positive current main, through the wire 4 and the wire 5,through the electromagnetic actuating mechanism of the register T thencethrough the upper switch contacts of the switch S thence through thewire 6 to the rotating time brush TB, which dips periodically into themercury trough MT, which is connected with the negative current main. Itis to be noted that whenever a workmans controlling switch is closed,the circuit of the associated time register will be closed overa'circuit such as that just traced through the switch contacts TB andMT. If, therefore, the shaft upon which the brush TB is mounted to berotated at a uniform speed, proportional to the lapsation of time, thetime registers will be actuated by impulses flowing with a frequencywhich will cause them to indicate at all times the number of hours withwhich the respective workmen are to be credited.

If, now, we take up a little more fully a consideration of the selectorswitches and the rate controlling switch and contactor, we shallunderstand more clearly how the wage registers are operated to accountwages. At DM, is indicated the driving motor, which is supplied withcurrent from the positive and negative mains over a circuit which may betraced through the wire 4 to the brushes of the motor, thence to thefull resistance contact of a regulating switch RS, thence through theswitch arm to the wire 7 leading to the contacts of a governingrheostat, GR. Normally, the circuit may be traced through the switch arm8 to the wire 9, and thence to the negative terminal of the directcurrent source, not indicated. With substantial constancy, the motor DMoperates to rotate its shaft and, by means of the gearing indicated, todrive the shaft of the time brush, TB, in'the direction indicated by theassociated arrow-head. In

the system shown in the drawings, the time brush TB dips one hundredtimes per hour into the mercury trough MT. l'he gear ratios of theelectromagnetically actuated time registers are such that one hundredimpulses flowing through the electromagnet will cause an increment ofone hour to be registered by the associated numeral wheels.

The wage rate contactor comprises the wage brush VB, carried by andinsulated from the shaft of the motor DM and the mercury trough MT, intowhich also this brush is adapted to dip. In the system shown in thedrawings, the shaft of the motor DM revolves at the rate of four hundredtwenty revolutions per hour whereby the wage brush WB causes the flow ofseven current impulses per minute. At RC, in Fig. -l, is verydiagrammatically illustrated the rate controlling switch. Withoutstopping now to describe the details of its mechanism, let it beunderstood that at the beginning of every minute ;he rate controllingswitch is given a one-step advancement. The result is to open or closethe appropriate switch contacts diagrammatically shown, as may berequired to cause the flow of the proper number of current impulses.Assuming that workman N o. 1 is to receive twenty-five cents per hourfor his labor, the rate controlling switch mechanism will cause theclosure of the contacts R and R0 twenty-five times per hour, and duringeach such closure of the rate controlling contacts, the wage brush VBwill dip seven times into the mercury trough MT to cause the flow ofcurrent impulses. Not all of the seven impulses will, however, flowthrough the circuit closed between the contacts R0 and RG because only asingle wage register is connected by the plug RP with the strip ofspring jacks connected with the contact RC, and the closure of thecircuit through this wage register \V depends also upon the connectionof the segments C and (1 of the selector switch with the associatedbrushes. This selector switch connection with the circuit of the wageregister \V is maintained only during a single revolution.

of the wage brush WB. The mechanism is as follows: l pcn the shaft uponwhich the wage brush \VB is mounted, there is mounted also a one-tootheddriving disk, DD. The tcoth of this disk is adapted to mesh in thenotches in the periphery of the locking disk LD, whereby each revolutionof the shaft of the motor DM causes the one-step advancement of theshaft 3, which carries the brushes of the selector switches. Sevenrevolutions of the wage brush cause, therefore, a complete revolution ofthe shaft 3 and the selector brushes. The result is that the circuits ofthe sin wage registers "are closed in succession, one after another, andduring the closure of each such' circuit, the wage brush W13 clips oneeinto the mercury trough to cause the fioiv of a eurrent, impulse throughany register whose rate eontrolling plug is intsertetl ln a spring jaekconneetetl \\ltl1 a rate eontrolling eontaet WllOFt, eireuit is tlOStdat that time.

It will he noted that the seleetor switch eonnnutators contain one moresegment than there are wage registers.

Having described inthis way the electrical operation of the ratecontrolling switch, it may be well to describe a little more fully themechanical construction which I have devised to accomplish the necessaryresults. The details of the rate controllingswitch are illustrated inFigs. 2 to 8, inclusive. The switch contacts which are designated inFig. 1 as BL and R are marked with the same reference characters in Fig.2. These switch contacts are ident cal with those shown at RC and RU Theupper contacts are insulated from one another. All of the lower orspring contacts are connected together and with the frame of the ratecontrolling switch, his multiple connection of the lower contacts beingindicated in Fig. 1 by the wire 10, which leads to the wage brush 'B.Each of the upp'er or stat'onary contacts of the rate controlling switchis connected with a strip ofspring jacks. as indicated in Fig. 1. Justabove the strip of spring jacks which is connected with the contact RCis located a smaller strip of spring jacks connected by a wire, notshown, with the stationary contact which delivers say thirtyseven and ahalf impulses per llO'll', it being understood that over-time iscredited at the. rate of time and a half. Each strip of regular springjacks may have associated with it a set of over-time spring jacks inthis manner.

Each of the motor springs, such as RU and RC. is adapted to be actuatedby a pivoted actuating arm PA. Each arm is equipped with a hardenedroller HR, which rides on the periphery of a rate d sk such, forexample, as that marked RD A number of rate disks are illustrated infront elevation in Fig. 2. Those shown deliver-impulses respectively atthe following rates, in

cents per hour, reading from left to right:

All of the rate disks are slipped upon the common spindle CS, therebeing a feather and suitable keyways in order to aline the disks uponthe shaft and to prevent slipping. A suitable nut serves to clamp thedisks in position between the intervening collars. Each rate diskcontrols the position of the associated actuating arm PA, therebycontrolling the opening and closing of the associated switch contacts.

The spindle (S is intern'iittently advanced by the ratchet wheel RW.mounted at one end. The power shaft PS has a step bv step rotation inthe direction of the arrow shown' on the drawings, this rotation beingderived from the locking disk LD,

which is given a step by step rotation by the the rocking arm RA as itmoves from the position shown in the drawing. The cam surface is such asto give the rocking arm a movement suflicient to dvance the ratchetwheel RlV a single ste the motion being transmitted by the pawl PL.There are one hundred twenty teeth on the periphery of the ratchet wheelRVV, and the'movement is just sufficient to cause an advancement'equalto the space of onetooth. The wage brush, as previously stated, dipsseven times per minute into the mercury trough MT. '1 he locking diskand the power shaft PS are therefore given one complete revolution perminute; since every revolution of the power shaft causes the one stepadvancement of the ratchet wheel RWV, it will be clear that the ratchetwheel and all of the rate disks pill be given one completerevolution intwo iours.

The peripheries of the rate disks are sonotched as to cause the closureof the associated contacts during as many minutes as there are impulsesto be delivered duringthe two hour period. Thus, the 8 rate disk at theextreme left in Fig. 2 causes the closure of its contacts during sixteenminutes in every two hour period. The 25 rate disk causes the closure ofits switch contacts during fifty minutes in two hours. A few of the ratedisks are shown in side elevation in Figs. 5 to 8, inclusive. Fig. 5shows the disk properly notched for a rate of twenty-five cents perhour. Fig. 6 shows the disk notched for a rate of ten cents per hour.Fig. 7 shows a disk notched for a rate of thirty-two and a half centsper hour; and Fig. 8 shows a disk notched for a rate of twelve and ahalf cents per hour. This last disk is, of course, notched, aspreviously explained, so as to cause the flow of twelve impulses duringalternate hours, there being a flow of thirteen impulses during everyintervening hour.

Having now described the means by which the various rate disks areconformed to control the associated circuits so that current impulsesmay be sent over such circuits at desired rates, it is apparent that themain portion of the rate switchboard shown in Fig. 1 may be connectedwith the upper portion, adapted for over-time, in a manner indicated inFig. 17. Assuming that the various strips of jacks of the main rateboard are connected for 8, 10, 12%;, 15, 20, 22%, 25, 27-} and 30 centsper hour, respectively, the

corresponding over-time strips of jacks, assuni'ug that the over-time isto be paid at tour and a hall. would he so connected to the cin uitcontrolling (l sts as to correspond to rates ot 13. no. 22;, 30, 3:37.37;. ii and 45 cents per hour. respectively.

()l viousl v. other similar arrangements can hmade for other rates it o\er--time or For other rates per hour.

With this explanation of the rate control ling mechanism. a little morecomprehensive idea of the operation of the whole system ma) he gained.It will he apparent that the rate plug of any workmans circuit mav heinserted in anv of the spring jacks connect ed with the stationarycontacts of the rate eontrolling switch.

The rau'pose ot the one. or two. or three additional rotations or'aetuations of the wage hru 'h is merelv this: The rate eontrollingswitch is advanced hut once per minute. This advancement should taltoplace during an interval when no \\'t)t'l\' men's intlividtmL registersare in closed eir .cuit. By putting one or two or three [than]:

him. morning with his wage register at zero. Wlll' segments n theselector switch, as, for example, a seventh segment in the switch shownin Fig. 1. it is possible to cause the one step :ulvancement ot' therate controlling switch during that interval inwvhich the lit-a he ot'the selector switch are moving over the idle segments. The result isthat the mechanism of the rate controlling switch remains stationary andlixed throughout that part of each minute during which the worinncnsindividual registers are included in circuit hr the selector switch.There is no purpose in causing the wage brush to make the e\trai'cvoilttions and contacts except that in the mechanism shown theadvancement ot' the selector switch mechanism is controlled hv thedriving dislt mounted on the shaft of the wage lirushv it is. therefore.convenient to permit the wage brush to make the extra contacts, althoughno current is caused to [low as a result of these e\tra ct'mta 'rts.

It will he apparent that the operation of the mechani m thus fardescribed will cause eath worittnans wage register to indicate at alltimes the amount of wages earned by A workman starting in on Monday tnoon-time he ahle to read from his register the amount of wages he hasearned during the morning. 'hen he stops work at noontime. he may openhis individual switch as, for example. 3. therehv preventing the furthcrtlow of impulses through his wage regislet. When starting work again inthe afternoon. he closes his individual switch, wliere-ipon impul esagain tlow. causing the rc;.F --tct' again to l e actuated, whereupon atnight time he may real the total-of his wage for the day. It. as ispreferable, the wage register is not reset to zero at this time. thewages earned on Tuesday will he added to those indicated hv the \vageregister for ondav. At the end of the Week, th total of his wiiges mavhe read from the wage register. In o der for these results to heaccomplished with aecuracv it is, of

course. ne es ary that the current irnnulse mechanism he governedclosely. as by a clock. t\l\' invention provides such governing orregulating means. which may he dorihed as follows. with particularreference to Fig. l. I i

tictnl'ullt stated. the cheme of regulation onttmplates a tlll\lil fmotor. which has an autt'uuat r m chan sm t'nr stopping it at th end ione minute's operation. or. rather. th motor is autolntt rallv stoppedslightljv het'ore the end of a on uinute interval. clock er\c aatoma totrip or s tart the motor at the \".rl'i...1Httliltllt ot' each minute.This tarting ot' the Motor very acrui atelv controlled hr the 1 loch andtherei'orc it does not matte-r n l he." the l tis ot or too fifty-nineseconds before it is stopped. In any event, it is regulated so that itwill not run for more than a minute before it is stopped. The result isto make the operation of the motor and the impulse sending mechanismwhich is driven thereby, correspond with the elapse of time as measuredby the clock, and the stopping of the mechanism for one or two secondsbefore the commencement of each minute will not interfere in any waywith the proper operation of the system. The apparatus for carrying onthis mode of operation is illustrated in Fig. 1, where the governingclock is shown at GC. This clock serves, at the commencement of eachminute, to close a circuit which may be traced as follows: from thepositive main through the wire 11 to the controlling brush CB, thence tothe metal portion of the periphery of the controlling disk CD, thencethrough the wire 12 to the internal mechanism of the clock GC, where aswitch (not shown) closes the circuit at the commencement of eachminute. Continuing, the circuit may be traced through the wire 13 to thenormal contact 14, thence through the wire 15 to the electromagnet 16 ofthe governing rheostat GR, and thence to the negative main. \Vhen theelectromagnet 16 is energized, it attracts its armature to throw thelever 8 into its intermediate position, where a circuit through thedriving motor is closed as follows: from the positive main through thewire 4, through the driving niotor DM, thence through the resistances ofthe regulating switch RS to the wire 7, thence through the resistance ofthe governing rheostat GR to the lever arm 8, and thence through thewire 9 to the negative main. The full strength of the current is notpermitted to flow, on account of the resistance of the governingrheostat. The motor, however. starts and sets in operation the powershaft PS, which by the rheostat cam RC soon throws the lever 8 into itsfinal closed position, as shown in the drawings. The flow of currentthrough the electromagnet 16 is stopped by the opening of the switch inthe governing clock as soon the driving motor 1) has been well started.The rheostat cam serves, however, to hold the switch arm 8 in its closedposition during one complete revolution of the power shaft PS. The speedof the motor I) is such that shortly before the expiration of oneminutes time, the power switch PS will have rotated through a completerevolution, whereupon the roller of the arm of the governing rheostatwill drop into the notch of the periphery of the cam, thereby openingthe circuit which supplies current to the driving motor DM. This circuitwill continue open until the comnicnccmcnt of another minute, whereuponthe switch of the governing clock GC will be closed again to energizethe electromagnet 16, whereupon the motor will be started and caused torun, as previously explained. This cycle of operation will continue overand over again, it being apparent that so long as the speed of thedriving motor is such as to cause a complete revolution of the powershaft PS in slightly less than one minutes time. it is not material thatthe speed of the motor should be constant as is that of a clock.

It is many times desirable, in a system of this kind, that the impulsesshould flow onlv during regular working hours, as from 8 in the morninguntil 12 noon, and again from 1 until 6 oclock in the afternoon. Toarrange automatically for this operation of the mechanism, I provide thecontrolling d sk (D and the controlling brush CB. These are clock drivenby suitable gearing, as shown. The periphery of the controlling disk isof insulating material, except at those parts which come into connectionwith the controlling brush during the regular hours of work. \Vhen themetallic sector of the disk comes into contact with the controllingbrush at 8 oclock in the morning, the clock switch energizes theelectromagnet 16, whereupon the driving motor DM is started. and thisminute by minute energization of the electromagnet will continue until12 oclock noo'n, when the energizing circuit is opened by the engagementof the insulating sector of the controlling disk with the controllingbrush CB. Again, in the afternoon at the proper hour, the circuit isagain closed through the controlling brush and disk, whereupon theenergizing impulses flow again once each minute until 6 oclock p. m.,when they are again shut off for the night.

If it is necessary for some or all of the men to work over-time, and itis desired to pay all of them at an increased rate, it is but necessaryto throw the regulating switch RS into an advanced position, in whichthe resistance in the circuit of the driving motor DM will be decreasedand in which also the switch arm terminates the wire 15 will beconnected with the contact 17 instead of the contact 14. This contact 17is connected with a switch, not shown. in the mechanism of the governingclock GC. This switch instead of being closed at the commencement ofeach minute will be closed at. say, the crunnicnccment of eachforty-eighth second. The result is that the driving motor will bestarted once in each forty-eight seconds. instead of once in every sixtyseconds, and the decreased resistance in the circuit of the drivingmotor will cause that motor to run at a speed such that the power shaftPS will have completed a single revolution shortly before the expirationof the fortyeight seconds period. The result isthat the actuatingimpulses will be sent through the registers at 2H1 lllt'lifilt tll raten-epm'timmi to pay an the basis at time. :uul a: quarter for over-thin.it will. 11? rmiirim "lei" stuml that the t'ula i'nlli supply current fr the veer" (hiring the night; lllm' sax-y. timrctli u a switch (32* mtoit iill'illlllit nmtw an order that the eunent nu hr the per 31:: energaitnm 13% nie g net lift,

The iwliri hm. job registers are indicated at .3 J 2 J. Each 01'these job registers mum-ml h a wire Shawn, with a em 0% Spring jacks,the strips of jacks being indicated at JS JS J S. Tracing the flow ofimpulses coming, say, through the foremans plug FP we may assume thatthis plug is inserted in one of the strips of spring jacks marked J Ssuch an insertion of the plug by the foreman corresponding with theassignment of workman No. l to job No. 2. The impulses coming at a ratecorresponding with the workmans rate of wages, will flow from the stripof spring jacks through the wire to the electromagnetic mechanism of jobregister J", thence through the common wire which leads from all of thejob registers to the job total register JT, thence through a wire whichleads through wage magnet WM of the total cost register TC, thencethrough a wire whicl'vleads through the wage total register WT andthence by way of the wire 18 and the wires 5 and/l to the positive poleof the battery, or other source of current. It will be apparent that ifworkman No. 1 receives wages at the rate of 25 per hour,

and therefore impulses at the rate of twentyfive per hour, theseimpulses will flow at that rate over the circuit just traced, causingthe step by step advancement of all of the electromagnetic registermechanisms in the circuit. The flow of twenty-five impulses through theworkmans wage register will, therefore, be accompanied by thetwenty-five step advancement of the job register J the job totalregister JT, the total cost register TC and the wage total register lVT.The foreman may insert.

.the plug terminal of any other workmans circuit also in one of thespring jacks of the strip JS thereby causing another set of impulses toflow over the circuit just traced. In like manner, any number of theworkmen may be plugged onto job No. 2, and since no two impulses flow atthe same time, each of the totalizing registers in the circuit justtraced will be actuated by an amount corresponding with the total of thewagescained by all of the workmen assigned to job No. 2. In like manner,any one or more workmen may be assigned to any other job, andaccordingly the foreman may insert the plug terminal of the workmanscircuit in a gorrcsponding spring jack. No matter which of the jobregisters may thus be included in the circuit, all of the impulses forall of the jobs will flow through the job total register J T, thencethrough one of the electromagnetic actuating mechanisms of the totalcost register TC and thence through the wage total register WT. If therewere no other operation of'these totalizing registers, we shouldtherefore have in each of them an indication of the cost of the labor,on all of the jobs in process, each job register indicating the totalcost of the wages earned upon that .job. There are, however, manyaccounting operations which affect some or all of these registers. Inthe first place, the waste wages are added to the total which isindicated by the wage total register \VT, while this factor is not addedor indicated by the job total register JT. The reason for this will beapparent, when it is considered that the wire from the waste wage springjacks '5 leads through the foremans waste wage register FW', thence tothe managers waste wage register MlV, and thence to the total wageregister WT. Any workmen whom the foreman cannot assign to a productivejob are assigned by him to the waste wage class, their plugs beinginserted in the spring jacks of the strip \VS. Their current impulses,therefore, flow over the circuit just traced, and through the wage totalregister WT, but not through any of the job registers nor through thejob total register JT, nor the wage magnet of the total cost registerTC. The result is that the total ct the waste wages is indicated both bythe foremans waste wage register FlV and by the managers waste wageregister MW these being located at different points in the factory, andthe waste wages are added also to the indication of the wage totalregister WT, it being apparent that all of the current impulses comingfrom the workmens wage registers must flow through the total wageregister TVV, regardless of whether they reach this register through thewaste wage registers or the job registers and the totalizing registersin circuit therewith. 'e have, therefore, in the job total register JT acurrent showing of the total wages earned on all of the productive jobs.We have in the foremans waste wage register and in the managers Wastewage register a current showing of all of the waste wages, and we havein the total wage register WT a current showint of all of the wages,whether ])IO(lll0tl"8 or non-productive.

The operation of the totalizing registers is also, in some degree,affected by the mechanism which my invention provides for accounting thematerial which enters into a completed job. In other words, my inventionprovides an automatic means for securing not only the total wage cost ofthe various jobs, but, for securing in addition the material cost. As aresult of this ar rangcment, each job register indicates not merely thetotal wage cost of the job, but the total of wages and material.Generally speaking, the material cost is handled by a keyboard mechanismadapted to send any pie-determined number of current impulses at a highrate of speed. If, for example, material is issued against a job to theamount of thirty-eight cents, the key-board mechanism may be setmanually to send thirty-eight current impulsesf If material is issued tothe amount of $4.67, the keyboard mechanism may be as readily set forthis zimount, whereupon four hundred sixty seven current impulses willhe sent at :1 high rate of speed These current impulhes are directed bysuitable frfiYltCltlEagI lllt.liilliih ll through the electroinagnetir.notion m llltt'll unism of the proper jol r gister: 'lhtvircuits overwhich these nninunlly ront'rolleti impulses are sent contain alsoVarious total izing regietrrs. which furnish a current showing ofunportnnt net :unl 'iuiil win.

Wage(JOlilPltHllC-Ilt of the reading n the Wtlfit. total register WVT, whichis to be cleared. Accordingly, with this set-up, the interrupter switchsends out a number of impulses corresponding to the complement of thereading to be cleared, with the result that the numeral wheels of thecurrent wage total register are advanced to their zero position. Theelectromagnetic driving mechanism of the prior wage total register \VTis arranged to actuate the numeral wheels of that register in thereverse direction. The result is that while the complemental number ofimpulses restores the current wage total register to its zero position,it actuates the numeral wheels of the prior wage total register WT inthe reverse direction by an amount equal to the key-board set-up. Inother words, the complemental number is subtracted from the indicationon the face of the prior wage total register. To take a concreteexample, it may be assumed that the current wage total register hasthree numeral wheels and the prior wage total register four numeralwheels. If, under these circumstances, the reading of the current wagetotal register is 750, the key-board set up will be 250, which is thecomplement of 750. Two hundred fifty impulses will, therefore, flow toadvance the numeral wheels of the current Wage register to 000 position,at the same time subtractin 250 from the reading of the prior wageregister. If this register is started from its 0000 position, the resultwill be an indication of 9750. This reading will be correct as to the750, but the 9 must be corrected in order that the correct amount shouldappear. -This correction is accomplished by an auxiliary electromagnetwt, which, when energized, acts to advance the highest order wheel ofthe associated register one step. The mechanism for ac-v complishingthis end will hereinafter be more fully described. Sufiice it for thepresent to explain that the circuit of the electromagnet 1023 isautomatically closed upon the insertion of the accountants plug in thespring jack G, there being auxiliary switch contacts 9 Which are closedupon the insertion of the plug. These auxiliary contacts control theflow of a current impulse, which, upon the actuation of the go key KG,may be traced from the negative pole of the battery or source of currentthrough the g0 key, thence by wire 20 to one of the auxiliary contactsg, thence from the other contact of this auxiliary switch through theelectromagnet wt to a common wire which leads to the Wire 5, and thenceto the positive pole of the battery. The flow of a single currentimpulse over this circuit advances the numeral Wheel or Wheel of theprior wage total register WT to ctrrect the error in the reading of thisregister which would otherwise result from its reverse actuation by anumber of impulses equal to the complement equal to the direct readingwhich is cleared from the current wage register. It will be seen fromthis description that the mechanism is pre-arranged in a manner suchthat the current wage total register cannot be cleared except as theprior wage total register is counterbalancingly actuated. The result isthat the current Wage total register may be cleared at the end of theweek or other pay-roll period, while the prior wage total register willindicate the total wages to date, as, for example, from the beginning ofthe fiscal year.

If it be desired to clear an individual time register into the currenttotal time register TT, the accountants primary plug is inserted inspring jack J and the secondary plug in the spring jack associated withthe individual time register to be cleared. Thus, for example, if timeregister T is to be cleared, the accountants secondary plug will beinserted in the spring jack of the individual time register T. Theoperator then sets up upon the key-board the complement of the readingof the register T and depresses the go key KG. This sets in operationthe interrupter switch, whereupon the complemental number of currentimpulses is caused to flow over a circuit which may be traced asfollows: From interrupter brush 1B through the tip of the plug AP, thetip spring of the jack J, thence through the electromagnetic mechanismof the toal time register TT to the sleeve spring of the jack J, thencefrom the sleeve of the plug AP to the tip of the plug AI, thence fromthe tip spring of the spring jack of the register.

' error due to the flow of the complemental number of impulses insteadof the direct number. W'ith this descriptio and 'what has gone before,it will be un erstood how the individual time registers may be clearedsuccessively, oneafter another, whereby the total of the readings of theindividual registers will be made to a pear on the face of the totaltime register T.

It is to be noted that the individual time registers are actuated byimpulses which flow simultaneously through all of the time registers,this eing in contradistinction with the individual wage registers, in notwo of which an actuating impulse flows at cannot be actuatorurnuhurrrntly b i (in: tiuw of the impulses whirh actuate the individualregisters when the impulses flow simultane ously through all of them asin the case of the time registera hut he hey-hoard inipulsemeuhunisinjust duscrilw-z'i enables the total of the mailings of the indiridualregi; ters to be indicated automatimlly an the in dividual rvgisters areiv-2;? in fiiwir 2m n positions.
